PRESSED METAL SPINNING RING HOLDER Filed Sept. 1, 1953 1 l9 ATTORNEYS Patented May 29, 1934 UNITED STATES PATENT OFFICE Application September 1, 1933, Serial No. 687,759 In Japan May 26, 1933 4 Claims.

This invention relates to holders for spinning rings formed by press work from short pieces of metal tubes or metal plates. In the attached drawing the figure shows the holder in which (1) is the ring rail, (4) is the portion to flt the holes in ring rails of spinning frame, (2) is the portion or" the holder made suitable for fitting the rings in place, (3) is the slot cut in the portion (2) to provide spring to snap-in the rings in place.

Ordinarily such holders are made either of cast iron machine-finished to the required form or of flat steel plate provided with raised clips to secure the ring flange. The former on account of the nature of the material cannot be made light in weight and slight in section. The latter being flat in entirety except at the clips needs to be secured in place by screws or such other means.

The advantages contained in the holders of this invention consist in by lightness of weight, a superiority over cast iron holders, in that the space directly below the out side of top ring flange can be made much greater than possible with case iron holders so that the manipulation of putting on and taking off ring travellers held at operators finger ends can be performed with greater ease.

Having thus described my invention what I claim is:

1. A holder for spinning rings comprising an annular piece of sheet metal which is bent outwardly and then inwardly upon itself intermediate its length to form a supporting flange, an upper, spinning-ring-supporting annulus and a lower annulus adapted to be received in a ring rail, the upper, spinning-ring-supporting annulus being slotted to give it suflicient resiliency for the insertion and retention of a spinning ring.

2. A holder for spinning rings comprising an annular piece of sheet metal which is bent outwardly and then inwardly upon itself intermediate its length to form a supporting flange, an upper, spinning-ring-supporting annulus and a lower annulus adapted to be received in a ring rail, the upper, spinning-ring-supporting annulus having at least one slot extending downwardly from the top and terminating above the supporting flange to impart to it sufficient resiliency for the insertion and retention of a spinning ring.

3. A holder for spinning rings made of sheet metal comprising a supporting flange, an annulus extending downwardly from said flange and adapted to be inserted in an opening in a ring rail, an annulus extending upwardly from said flange and adapted to receive and support a spinning ring, the upper annulus having at least one slot extending downwardly from its upper edge but not extending below the supporting flange.

4. A holder for spinning rings made of sheet metal comprising a supporting flange, an annulus extending downwardly from said flange and adapted to be inserted in an opening in a ring rail, an annulus extending upwardly from said flange and adapted to receive and support a spinning ring, the upper annulus having at least one slot extending downwardly from its upper edge and terminating above the supporting flange.
